[README] Common (some unsolved) Problems in 10.12 Sierra

Hi, I recently upgraded from El Capitan to Sierra and am unable to get WiFi working. I applied the fcvo patch and installed FakePCID_Broadcom_Wifi.kext, FakePCIID.kext, BrcmPatchRAM2.kext and BrcmFirmwareRepo.kext. I still have 'Wifi: No Hardware Installed' message in the finder. :(

My Wireless Hardware: Dell Wireless DW1560 802.11 Broadcom BCM94352Z WIFI NGFF Card 6XRYC

Here is the result when I used "sudo touch /System/Library/Extensions && sudo kextcache -u /":

Here are the links I have read for reference, to try to fix it myself BEFORE seeking additional assistance:

http://www.insanelymac.com/forum/topic/312759-fix-macos-sierra-dp1-bcm94532z-wifi/
https://www.tonymacx86.com/threads/solved-kext-for-bcm4352.181902/#post-1172956

Any help would be appreciated. I don't mind buying someone a beer to help me out with this head scratcher. I wasn't sure if I should have created my own post, but since this thread is in the hundreds with similar posts as mine, I reckoned it would be safe to put it here. If I am wrong, please excuse me.

I will provide any additional information via request.

Thanks in advance!

Here are the links I have read for reference, to try to fix it myself BEFORE seeking additional assistance:

https://www.tonymacx86.com/threads/solved-kext-for-bcm4352.181902/#post-1172956

Any help would be appreciated. I don't mind buying someone a beer to help me out with this head scratcher. I wasn't sure if I should have created my own post, but since this thread is in the hundreds with similar posts as mine, I reckoned it would be safe to put it here. If I am wrong, please excuse me.

I will provide any additional information via request.

Thanks in advance!

The problem is obvious in your kextcache output. One or both of system WiFi kexts (IO80211Family.kext, AirPortBrcm4360.kext) are corrupt:
Code:
kxld[com.apple.iokit.IO80211Family]: The following symbols are unresolved for this kext:
kxld[com.apple.iokit.IO80211Family]:     CCIOReporterDataStream::getIOReporterRawDataForSubscription(unsigned long long)
kxld[com.apple.iokit.IO80211Family]:     CCIOReporterDataStream::getIOReporterInterestArrayForSubscription(unsigned long long)
Link failed (error code 5).
Prelink failed for com.apple.iokit.IO80211Family; omitting from prelinked kernel.
Can't use IO80211Family.kext - not linked.
Prelink failed for com.apple.driver.AirPort.Brcm4360; omitting from prelinked kernel.

Run the macOS installer to restore your kexts to vanilla.
 
how can I do this without losing my settings? Couldn't I just extract the offending kexts from the installer instead somehow?

If you run the macOS installer without erasing the target partition, it simply refreshes all your system files.
All settings/apps/data will be untouched.
 
brilliant, I will run the installer again now
 
I have solved my problem. Thank you.

Hi,

I am from France and i discovered this forum so I installed Sierra on my laptop a dell latitude E7450. Everything is working except brightness with is not saving. I loose my settings each time I reboot or after getting out from idle.

I have read a lot of posts without result.

What is the good way to make it work.

I don't use karabiner I prefer using apple standard settings from preferences.

Many thanks for your help

If you have a problem to report, you must provide "Problem Reporting" files.
 
Many thanks for answer, I'll test that tomorrow. if not successful I will provide needed files
 
This is it!
My u430 with 10.12.4 suffered from this problem (short duration lag after wake and after login).

My u430 has LVDS and a single HDMI.
I use ig-platform-id 0xa260006 with it. 0xa260006 has LVDS, 0105 DP, 0204 DP.
The HDMI is wired to 0204, so I patch that port for HDMI (to enable HDMI audio).
I also use the 'vbo' 9mb cursor bytes patch (even though it is not needed on my particular laptop... it is helpful on others).

So... before 10.12.4, I had these patches for com.apple.driver.AppleIntelFramebufferAzul:

Comment: 0x0a260006 9MB cursor bytes, vbo
Find: <0600260a 01030303 00000002 00003001 00006000>
Replace: <0600260a 01030303 00000002 00003001 00009000>

Comment: HDMI-audio, port 0204, 0x0a260005 0x0a260006
Find: <02040900 00040000 87000000>
Replace: <02040900 00080000 87000000>

Now the 0105 port comes before the 0204 port in the framebuffer, but we don't need the 0105 port as it is not connected to anything (and causing the lags).

So... strategy is to replace 0105 with 0204 and reduce the number of ports from 3 to 2.

We already know that in AppleIntelFramebufferCapri that 0x01660004 has only a single LVDS connector, so we can look to the header of that ig-platform-id data to discover what we need to reduce our ig-platform data in Azul from 3 ports to 2.

From AppleIntelFramebufferCapri 0x01660004:
04006601 01030101

And from AppleIntelFramebufferAzul 0x0a260006:
0600260A 01030303

So, there appears to be two counts at the end related to the number of connectors... plan to change them both...

New set of patches:

Comment: 0x0a260006 9MB cursor bytes (vbo), 2 ports only (RehabMan)
Find: <0600260a 01030303 00000002 00003001 00006000>
Replace: <0600260a 01030202 00000002 00003001 00009000>

Comment: 0x0a260006 disable 0204 port, change 0105 DP port to 0204 HDMI (RehabMan)
Find: <01050900 00040000 87000000 02040900 00040000 87000000>
Replace: <02040900 00080000 87000000 FF000000 01000000 40000000>

Result: No more lag after login and wake from sleep.

I have a similar issue (lag on startup/wake) with my setup, but my laptop has Broadwell using ig-platform-id 0x16160002. I'm guessing I would have to patch AppleIntelBDWGraphicsFramebuffer to disable the unused ports (my laptop has mini-DP and the built-in display), but I don't really know where to begin.
